Dental Sealants Kirkland
Protect your teeth from decay with our top-notch Dental Sealants service in Kirkland. A quick and painless procedure that offers long-lasting benefits for your oral health.

What Are Dental Sealants?
Dental sealants serve as a protective shield for your teeth, particularly the molars and premolars. These sealants are a thin, plastic coating applied to the chewing surfaces of your teeth to prevent cavities and tooth decay. In Kirkland, Thomas Dentistry offers this quick and effective treatment to help you maintain a healthy smile for years to come.
The procedure is simple, painless, and can be completed in just one visit. Dental sealants are especially beneficial for children who are more prone to cavities, but adults can also take advantage of this preventive measure. It’s an investment in your oral health that can save you time and money in the long run.
Sealants are a proven method for reducing the risk of cavities. They act as a barrier, sealing off deep grooves that are hard to clean and are prone to develop plaque. With dental sealants, you can eat and drink with confidence, knowing that you’ve taken an extra step to protect your teeth.
How Do Dental Sealants Work?
Dental sealants work by forming a smooth surface over the natural grooves and pits in your teeth. This makes it difficult for food particles and bacteria to hide, reducing the risk of cavities. At Thomas Dentistry in Kirkland, the process is straightforward and can be broken down into a few simple steps.
The application of dental sealants is a quick and painless procedure. First, the tooth is cleaned and dried. Then, an acidic gel is applied to the tooth’s surface to roughen it up, helping the sealant bond better. Finally, the sealant is painted onto the tooth and hardened with a special light. The result is a durable barrier against decay.
Process of Applying Dental Sealants:
- Cleaning: The tooth is thoroughly cleaned to remove any plaque or food particles.
- Preparation: An acidic gel is applied to create a better bonding surface.
- Application: The sealant is painted onto the tooth’s surface.
- Curing: A special light is used to harden the sealant, securing it in place.
With dental sealants, you’re taking a proactive step in your oral health. They offer an additional layer of protection that complements regular brushing and flossing.

Understanding the cost of dental sealants is crucial for making an informed decision. At Thomas Dentistry in Kirkland, we strive to offer competitive pricing without compromising on quality. While the cost can vary depending on various factors such as the number of teeth needing sealants, we offer multiple payment options to make the process more affordable for you.
We believe that preventive care like dental sealants should be accessible to everyone. That’s why we accept a range of insurance plans and also offer financing options. Our team is more than happy to discuss costs and payment plans with you, ensuring you get the best care without any financial stress.

Happy Client from Kirkland Office
“Went to that office last year to get a crown on implant and Dr. Thomas did the ugliest crown possible. Shape and height looked completely different from natural tooth I had in that place before. He did not even try to fix it. This year my new dentist confirmed that the crown should have been done completely different but now Im stuck with this crown for a while because it will cost a ton to re-do it since that is a dental implant crown, not just a regular crown. I guess I missed the first red flag when they said they do root canals and extractions too. Of course, why even going to roots canals specialists and oral surgeons if You can get a “buffet of services” at Dr. Thomas! Also Molly at the front desk is the rudest receptionist I ve even seen, billing office could not get the numbers right and overcharged me for about $800 then refunded but can this office be more unprofessional and thirsty for money?!!”
Madeleine Dow
Happy Client from Mercer Island Office
“Dr. Nguyen and the dental hygienists are super nice! I felt comfortable and safe—even the time I started crying when I had a panic attack before getting some cavities filled. (Sorry about that lol.) Anyways, Dr. Nguyen was very kind, gave me space to chill out, and didn’t make me feel embarrassed, even though I wouldn’t have blamed him if he did.”
